The Science of Politics

Vice President Kamala Harris has replaced Joe Biden as the Democratic nominee. And the conversation has immediately turned to race and gender. What do we know about how Black and Asian women candidates are treated by parties and voters? How does the Harris experience compare to others running for office? What does it mean for her ability to win in November and inspire a new generation of more diverse leaders? Jamil Scott has researched the unique features of Black women candidacies, from the decision to run to raising money to adapting to stereotypes. And she has also studied the increasing racialization of American elections. She tells me the typical tropes and conversations came immediately to this campaign.

In the midst of a harrowing political campaign, can Americans tone down their partisanship and unify around their common American values? Matthew Levendusky finds that Americans misperceive those in the other party and can improve their views if they are reminded of our shared national identity. From the Olympics to the 4th of July, some moments remind us that we have more in common than we may think. But reduced animosity also requires knowing real people on the other side of our divides and building cross-partisan friendships.

Democrats and Republicans rely on partisan think tanks for policy proposals, along with the numbers and findings that justify them. How did think tank research reach a central place in our politics and how influential are they? E. J. Fagan finds that partisan think tanks like the Heritage Foundation helped polarize the congressional issue agenda and debate, replacing the non-partisan expertise that Congress used to rely on. Conservative think tanks are gearing up for a possible second Trump administration while Biden’s policy agenda remains reliant on the liberal side of the think tank establishment.

The impact of racial attitudes in American politics isn’t just about the presence or absence of anti-Black prejudice. Some White Americans say they are highly sympathetic to the plight of Black Americans. Are they just placing Black Lives Matter signs in their yards or does it translate into political views and actions? Jennifer Chudy finds that many White Americans, especially liberal Democrats, have sympathy that translates into support for redistributive social welfare policies and opposition to punitive criminal justice policies. There is a growing and important left side of Americans' racial views.

We have overestimated the influence of partisan misinformation during political campaigns. But that doesn't mean we're well-informed. Americans know little about important public policy issues and they "know" things that aren’t so. Emily Thorson finds that Americans concoct information about current policy to match what they think they know. It's not that they are fed misinformation but that the media report little about the details of current policy, leaving voters to make up the facts. Correcting this misinformation about existing policy can make a difference and help Americans evaluate new proposals for policy change.

Robert F. Kennedy Jr is polling higher than prior third party candidates and his supporters could make the difference in a close election. Americans say they want a third party, but is this what they had in mind? Jonathan Cervas finds that in 2020, third parties actually took more potential votes from Republicans than Democrats. Victor Wu finds that lots of Americans say they want a third party. But most partisans seeking third options clearly favor their side’s issue positions. There’s not much of a constituency for a grand unity ticket in the middle.

Despite popular resistance in each party, Congress just reached wide bipartisan agreement on military aid to Israel, Ukraine, and Taiwan along with a forced sale of TikTok. Even in a polarized age, Congress has managed bipartisan votes on controversial issues in an election year. Jordan Tama finds that bipartisan coalitions are quite common in congressional consideration of foreign policy—from overlapping competing alliances to broad support for internationalism, Congress is far less polarized on foreign policy than domestic policy. William Bendix finds that legislators are consistent in how they sponsor foreign policy bills based on their ideological views even across administrations of different parties. He also finds that hawks usually lead and win congressional votes over doves, regardless of who is president.

Joe Biden is facing re-election shepherding an unsteady economy through high interest rates. Is this Democrats' bad economic luck repeating itself? Joe Stone finds that Democratic presidents have regularly expanded economies at the beginning of their terms but Republicans benefit from expanded economies leading up to the election. And partisan misalignment with the Federal Reserve also dampens economic performance. William Clark finds that the Fed raises interest rates as elections approach under Democratic presidents and lowers them for Republican presidents. And the Fed is more responsive to inflation under Democratic presidents. They both say the historical patterns may help explain why Biden finds himself in a more difficult position.

Our jobs shape our politics, including whether we run for office and which side of the political spectrum makes us feel most comfortable. Just as we are polarizing geographically, even our workplaces are now more likely to be filled with those who agree with us about politics. And our politicians come from these workplaces, often taking the specific concerns of their occupations with them. Max Kagan finds that you are most likely to encounter fellow partisans in your workplaces, partly because metro areas, occupations, and industries are politically homogeneous, and partly because we select into workplaces that share our politics. Jack Landry finds that state legislators bring their occupational concerns with them to legislating, shaping their committee assignments, campaign contributions, and personal financial interests. They both say it’s a complicated causal chain: we may segregate our work interests because of factors related to politics but we could also be socialized into the norms and interests of the places where we work.

Congress is fearful of TikTok’s influence, but America’s young people increasingly see it as a key platform for learning about and spreading political ideas. Will TikTok get young people engaged in the 2024 election or serve as another distraction? Neta Kligler-Vilenchik finds that young people embody an expressive citizenship, where you should speak out if you see injustice, and have found TikTok to be a fruitful platform. But she doubts that older politicians have figured out how to use it for effective persuasion. Richard Fox finds that TikTok users are liberal and more active, online and offline. But they take politics less seriously. He sees the same complaints about media change that scholars have been making for generations: we're favoring shorter, less substantive, and emotional clips over real learning. They both say we should be skeptical of TikTok remaking politics but that we should listen to young people, who see real change.
